Looking for reliable, friendly team to have fun playing competitive games

Looking for a team that plays regularly on competitive level, but with the focus on having fun!

Was silver in west Europe before recently moving to the States, now on my way to level 30 again. In Europe I played a lot of support. Without having a team and playing < level 30 I practiced all other positions the last months. I'm good as support, top and mid player, okay as jungler, so lala as ADC. Would prefer playing with adults (21+), would enjoy having a friendly and reliable team, could spent 2 days a week. A team in Bay Area would be nice (but not mandatory), so we can meet and have a beer together some day.
